The Ultimate Guide to 1630E324D Swing Gearbox: Everything You Need to Know

Best practices include regular inspection and replacement of hydraulic oil and filters, keeping the system clean, regular inspection and tightening of all connections, and monitoring system pressure and temperature.

Digging powerlessness can be divided into two situations: one is digging powerlessness, the engine does not hold back, and the load feels very light; the second is digging powerlessness, when the boom or dipper stick is extended to the bottom, the engine is seriously held back or even stalled.

①, digging powerlessness but the engine does not hold back. The magnitude of the digging force is determined by the output pressure of the main pump, and whether the engine holds back depends on the relationship between the oil pump absorption torque and the engine output torque. The engine does not hold back, indicating that the oil pump absorption torque is small and the engine load is light. If the working speed of the excavator is not obviously abnormal, the maximum output pressure of the main pump, that is, the system overflow pressure, should be checked in particular. If the overflow pressure measurement value is lower than the specified value, it indicates that the overload overflow valve setting value of the hydraulic circuit of the mechanism is incorrect, resulting in premature overflow of the mechanism and powerlessness. The machine can be adjusted by turning the adjustment screw.

②, digging powerlessness, engine holding back. The engine holding back indicates that the absorption torque of the oil pump is greater than the engine output torque, causing the engine to overload. This fault should first check whether the engine speed sensing system is normal, and the inspection method is similar to the engine inspection method described above. After the above detailed inspection and troubleshooting, the engine speed sensing system will resume normal function, the engine stalling phenomenon will disappear, and the digging force will return to normal.

Abnormal noises from the hydraulic pump may be due to air entering the hydraulic system, contaminated hydraulic oil, or internal wear of the hydraulic pump. Check the condition of the hydraulic oil, inspect the suction line for leaks, and replace the hydraulic pump or related components if necessary.

If the engine has trouble starting, first check the battery charge and connections. Ensure the fuel system is supplying fuel by inspecting the fuel pump and fuel lines for blockages. Check the glow plugs (for diesel engines) or spark plugs (for gasoline engines) for wear and replace them if necessary. Use a diagnostic tool to check for any fault codes that might indicate issues with the engine control unit (ECU) or sensors.

Possible restricted fluid flow, cooling system failure, or high oil viscosity.

Solution: Check and clear restricted areas, check and repair cooling system, use correct viscosity oil.
